Abstract | The Old Fort Point Formation of the Jasper anticlinorium comprises some 1200 feet of argillite, siltstone, limestone, and limestone-breccia, probably Precambrian in age. The sequence, divided into four members, probably records the westward migration of an ancient delta. Member A, the oldest, displays some 350 feet of argillaceous bottomset beds, while the overlying 500 feet of member B strata represent the foreset beds, characterized by numerous lenses of intraformational limestone-breccia. A break in the orderly sequence of events is recorded by the several hundred feet of homogeneous argillite of member C. However the 150 feet of silty argillite and siltstone of member D, overlain conformably by sandstone and quartz pebble conglomerate of the Miette Formation probably represents the final phase of the transition from fairly deep water, to very shallow water deposition. |
